Presented at: Third International Workshop On Ontology Matching (OM2008)
by Christian Meilicke, Heiner Stuckenschmidt
Traditionally, the quality of ontology matching is measured using precisionand recall with respect to a reference mapping. These measures have atleast two major drawbacks. First, a mapping with acceptable precision and recallmight nevertheless suffer from internal logical problems that hinder a sensible useof the mapping. Second, in practical situations reference mappings are not available.To avoid these drawbacks we introduce quality measures that are based onthe notion of mapping incoherence that can be used without a reference mapping.We argue that these measures are a reasonable complement to the well-knownmeasures already used for mapping evaluation. In particular, we show that one ofthese measures provides a strict upper bound for the precision of a mapping.
